Experimental data on the selection of optimal exposure modes of femtosecond radiation on a multilayer coating for selective ablation are presented.
Based on the obtained experimental data, the following conclusions can be drawn.
In contrast to the classical approach to the formation of such structures by laser radiation of nano- and millisecond duration, or by means of the photolithography procedure, the use of femtosecond radiation of a small waist diameter makes it possible to achieve a reduction in the gaps, as well as the overall dimensions of the elements (Fig. 4).
Such antennas are of interest for high-speed wireless data transmission, Thz-location, contactless scanning systems.

With the weight-reduction requirement for transportation tools, more and more carbon fiber reinforced plastics (CFRPs) will be applied.
These datas and design method will help us predict the resistance capability of CFRP structures on impact loads, and provide theoretical guide for the design of composite panels subject to repeated low-velocity impact loads.
During the testing, bending force-deflection curve is recorded by the data acquisition system.
Then, substituting these data along with the width and the thickness as well as the span of the specimens into eq.(1) and eq.(2), the residual bending modules and the corresponding bending strength were calculated when the impact number is one, or two, or three.

The data obtained from this work can be used for subject specific therapeutic methods.
The findings indicate that gait velocity data reported from long walkways tend to be higher than data obtained a short walkway also the gait pattern is different in indoor and outdoor gait.
These data can be further used for the therapeutic purposes.
The data was transmitted to PC via bluetooth at baud rate of 9600 bps.
The filtered data showed reduced peak amplitude and noise.

Permanent magnet with the 4500 Gauss power is compared in this experiment with the natural frequency to obtain the required data during machining.
Frequency data will be recorded by using DasyLab 5.6.
Once the data has been collected, it needs to be store back into RSM back for analyzing.
The data will be collected to determine the natural frequency area, acceleration amplitude and the frequency of tool holder during machining.
Since the highest percentage of vibration amplitude reduction was obtained for run number 1, these chips were observed.

Chemical analyses realized
by glow discharge mass spectrometry (GDMS) confirmed the reduction of the concentration of
these species.
Reciprocally, studying the nucleation and the growth kinetics of δ phase may allow to collect data about Niobium diffusivity.
So, in order to accelerate Niobium diffusion in alloy 718, the reduction of the alloy content of interstitial species seems to be a realistic hypothesis.
Finally, hardly any data on Niobium diffusion in Nickel and Nickel-based alloys are available.
Therefore numerous questions about the diffusion of Niobium in such alloy or about the interactions between interstitials content and Niobium diffusivity still remain and further work is needed to get both experimental data and advanced modeling of these effects.

Second, traversal-related: this focus on reduction of access times for objects.
The data objects are often in secondary storage and each data object is always potentially accessed or requested by more than one patterns.
The detailed data was shown in Table 1.
The APP approach uses tree-like data structure, a mechanism that calculates a probability by counting the frequency of values and combinations of values in the historical data.

The test took 60 days and 15 hours a day to obtain 900 valid datas.
Tests were carried out for two months, the test time is from 9:00 am to 11:00 pm in a day, and data is recorded once per hour.
Test observation shows that all datas are relatively stable and consistent whether the datas of 10 days before July 15th or those of 10 days after July 15th, so the subsequent data analysis uses the data of July 15th, in which the # 2 and # 3 chillers were come into operation, whose nominal refrigerating capacity is 2.474×103 Kw, and the other two being maintenance.
In order to express clearly each parameter changing with time and the relation between the parameters, this paper sorts the measured datas and draws up Fig.2 to Fig.7.
According to the measured data, the relationship between the chiller COP and chilled water temperature difference between inlet and outlet is drawn in scatter diagram as shown in Fig.8,similarly draw the relationship between the chiller COP and the chilled water outlet temperature shown in Fig.9.
